UPDATE: I’m leaving this series up for historical purposes, but please note that I no longer recommend Ubuntu Core or snaps for use in robotics. This is the fourth blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post we worked on getting data out of the wireless controller and into ROS in a format meant for controlling differential drive robots like ours: the Twist message....
UPDATE: I’m leaving this series up for historical purposes, but please note that I no longer recommend Ubuntu Core or snaps for use in robotics. This is the third blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post you were introduced to the Robot Operating System (ROS), and got your robot moving by ROSifying one of the CamJam worksheets. Today we’re going to move beyond the CamJam worksheets, and work toward having our robot remotely controlled by focusing on our wireless controller: getting data out of it and into ROS messages....
UPDATE: I’m leaving this series up for historical purposes, but please note that I no longer recommend Ubuntu Core or snaps for use in robotics. This is the second blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post we walked through all the hardware necessary to follow this series, and introduced Ubuntu Core, the operating system for IoT devices. We installed it on our Raspberry Pi, and used it to go through the CamJam worksheets....
UPDATE: I’m leaving this series up for historical purposes, but please note that I no longer recommend Ubuntu Core or snaps for use in robotics. Some time ago I created a blog/video series that walked the reader through creating a prototype using the Robot Operating System (ROS) and taking it to production using Ubuntu Core. However, that series was intended more for robotics professionals; it assumed quite a bit of ROS knowledge, and required some costly equipment (the robot was about $1k)....
Tomorrow, it begins. The culmination of weeks of research, documentation, and preparation by multiple open-source projects, just waiting to start hacking away with students. Tomorrow, students aged 13-17 can begin participating in Google Code-in 2017. Ubuntu is one of the mentoring organizations, with several of my colleagues and me as mentors. Just in case you haven’t heard of it, Ubuntu is an open-source operating system for servers, desktops, and embedded devices....
